STEAM RADIATOR.

Application filed June 16, L921.

the radiator has its steam-supply passage underlying the discharge passage, and my general object is to produce a radiator of this class in which the heat radiation elements are maintained at their maximum efiiciency and thereby minimize the cost of operation through the use of the smallest possible number of radiator sections.

A further object is to produce a sectional radiator of such construction that it has the greatest possible freedom of expansion and contraction without in any way impairing the connections between the sections or'the sections themselves, as is frequently attendant upon radiators Where the'connections are made at the ends of the sections, as in this latter type of construction the freedom of expansion of the sections is restrained and as a result frequent repairs and replacements are necessary.

A still further object is to produce a radiator which will not only be relieved of the defect of air-binding or water logging, but in which repairs may be made to an intermediate section without taking down the radiator or arresting the operation of the same.

A still further object isto produce a radiator of strong, simple, durable, efficient, and inexpensive construction, and in order that it may be fully,understood, reference is to be had to the accompanying drawing, in which:

Figure 1 is a top plan view of a radiator made up of three sections embodying the invention.

Figure 2 is an elevation of the exhaust side of a section.

Figure 3 is a section on the line III-III of Figure 1.

In the said drawing, where like reference characters identify corresponding parts in 'all of the figures, 1 are any suitable supports for the radiator. It will be understood that each radiator may be made up of a single section, or if the dimensions to be heated Serial N0. 478,002.

are large, of a large number of such sections (in the drawing a three section radiator is illustrated). Each section consists of a base member B which is formed with a pair of chambers'2 and 3 divided by a partition 4-. are a series of pipes5, closed at their upper ends by caps 6 or in any other suitable manner, each of said pipes enclosing a smaller pipe 7 which extends upwardly close to the closure of pipe 5 and is open at such end and at its lower end communicates with chamber 3 (see Figure 3).

A large flange 8 is formed on each side face of each section, and against one of said flanges a plate 9 provided with a steam inlet opening 10 communicating with a steam line 11 is adapted to be secured by means of bolts 11, which in the construction illustrated, shows a radiator made up of three sections, and said bolts passing through the flanges of each bank and fastening the whole rigidly together.

Abutting the other flange 8 at the opposite side of the radiator a plate 12 is secured by means of the bolt 11, by preference, and said plate carries an outlet opening 13 to which is connected a drain pipe 14 for the escape of ,water formed by the condensation of steam in the sections which will run down from the sections into chamber 2 and out through the drain and back to the boilers. It will 'be evident that with this construction, that is the steam underlying the water chamber, that such water will be highly heated just prior to its return to the boiler.

' It will be readily apparent from the drawing that steam entering chamber 3 will, un-

der pressure, pass upwardly through pipes 7 and escape into pipes 5 where it will gradually be condensed and flow downward into chamber 2 and from there, after being heated by the steam in the underlying chamber 3, will flow out through drain pipe 14, the construction being such that no airbinding or water-logging can occur. In order to provide means for theescape of water produced by condensation in passage 3 after the entry of steam has been shut off, a small pipe 15 connected with an opening in plate 12 communicating with chamber 3 is provided, the opposite end of said pipe communicating with the drain pipe 14, by preference, as illustrated. It is, of course, apparent that when steam is readmitted to chamber 3 any water which may be standing Communicating with chamber 2 therein will be forced out through drain pi e 15.

rom the above description it will be ap parent that I have produced a device of the character described, which possesses all of the features pointed out as desirable, and while I have described and claimed the preferred embodiment of the same, I reserve the right to make all changes properly falling within the spirit and scope of the appended claim.

I claim:

A radiator comprising a plurality of rectangular base sections arranged in sidewise abutting relation and each having superposed chambers and provided in its opposite sides with superposed openings, corresponding openings in the abutting sides of the sections registering with each other; plates fitting against and secured to the front side of the first and rear side of the last section through the same with the upper opening in the rear side of the last section, tubes secured in the tops of the sections and communicating with the upper chambers thereof respectively, and closed at their upper ends, and smaller tubes open at both ends, extend ing within the first-named tubes and communicating at their lower ends with the lower chambers of said sections respectively and at their upper ends with the respective enclosing tubes.

In witness whereof I hereunto aflix my signature.

JOHN T. HOPE.
